Native Blog Search improved!

Edit: I've updated the instructions and code since some people were complaining of it not working. I'd also like to mention that for some reason, external data calls aren't supported from the preview page, so please save your template, and try it again from your home page. If it still doesn't work, I'll be glad to help!

Update: I've made a few more changes, to make it check if it needs to paginate the results. Plus, a ironed out a few bugs.

---

It's been quite a long while since this hack was updated, even though it's been my most successful one! I'm sorry about that, but I guess it's better to follow the 'If it ain't broke, don't fix it' method. But I can sure as hell improve it! :P So now I present to you a slightly updated version of NSS. The original and first version can be found here! :)

This update was triggered mostly by Avatar's list of ideas for coders to tackle. If you think you have what it takes to tackle the others, check out the post here. Now, on to the hack itself. The only change at the moment is that you can now access results as an AJAX pagination type approach. Your results are preceded by the number of posts being shown, and a link to get the previous or next 10 results. I'll be soon adding a Google AJAX type search for other blogs, or Google services (as demonstrated on Hoctro's blog). I'm not adding that in this update because it'll need some major changes to the implementation, for which I need to come up with a simpler explanation than the one I have at the moment. That update to the hack itself is complete though ;)

The code

You might as well start by removing all the previous code, since all the functions have been updated. This will not confuse you later on! Start by adding this piece of code in your area of the template:

<script language='javascript'>
//<![CDATA[
var blog_name="BLOG'S NAME";
var _num=0, _para, p;

function $()
{
  for( var i = 0, node; i < arguments.length; i++ )
    if( node = document.getElementById( arguments[i] ) )
      return node;
}

function d_script(para, num, paged){
_para = para;
_num = num;

var url = (p=='paged') ? "http://xoxotools.ning.com/outlineconvert.php?output=json&classes=item&url=http%3A%2F%2Fblogsearch.blogger.com%2Fblogsearch_feeds%3Fq%3D"+_para+"%2Bblogurl%3A"+blog_name+".blogspot.com%26hl%3Den%26ui%3Dblg%26ie%3Dutf-8%26num%3D10%26output%3Drss%26start%3D"+_num+"&submit=Convert&callback=json" : "http://xoxotools.ning.com/outlineconvert.php?output=json&classes=item&url=http%3A%2F%2Fblogsearch.blogger.com%2Fblogsearch_feeds%3Fq%3D"+_para+"%2Bblogurl%3A"+blog_name+".blogspot.com%26hl%3Den%26ui%3Dblg%26ie%3Dutf-8%26num%3D100%26output%3Drss&submit=Convert&callback=json";

var script = document.createElement('script');
 script.type = 'text/javascript';   
 script.src = url;   
 script.id = "app-script";
 document.getElementsByTagName("head")[0].appendChild(script);
}

function json(rss){

 function paginate(){
    if(_num>=10) {
   $('stext').innerHTML="<div class='search-paginate-links'>Displaying "+(_num+1)+" to "+(_num+10)+". <a id='prev' href='javascript:d_script(\""+_para+"\","+(_num-10)+")'>Previous 10</a> | <a id='next' href='javascript:d_script(\""+_para+"\","+(_num+10)+")'>Next 10</a></div><br />";
   }
  else {
   $('stext').innerHTML="<div class='search-paginate-links'>Displaying "+(_num+1)+" to "+(_num+10)+". <a id='next' href='javascript:d_script(\""+_para+"\","+(_num+10)+")'>Next 10</a></div><br />";
   }
}
 
 function display_search(){  
  $('stext').innerHTML='';
  $('stext').style.display="block";
  $('stextcont').style.display="block";
 }
  
 var i=0;
 var results = [];
 if (!rss.item) {
  alert('No Entries\!');
  }
 else if(typeof(rss.item[1])=='undefined') { 
  results.push(rss.item); display_search(); 
  }
 else {
  results=rss.item; display_search();
  alert(results.length);
   if(results.length>=10){
    paginate();
                p = 'page';
   }
  }
 
 for(i=0;i<10;i++){
  app=document.createElement('a');
   app.href=results[i].link;
   app.innerHTML=results[i].title;
   app.title=results[i].title; 
  dv=document.createElement('div');
   dv.innerHTML=results[i].description;
  sp=document.createElement('br');
  
if(app.innerHTML!='undefined' && dv.innerHTML!='undefined'){
  $('stext').appendChild(app);
  $('stext').appendChild(dv);
  $('stext').appendChild(sp);
  }
else
  $('stext').appendChild(document.createTextNode('No results!'));
  }
}
//]]>
</script>

Just put in the name of your blog in the variable named 'blog_name' right at the top! For example, this blog would have it as 'var blog_name="lastword";'. Update: The links positioning can now be styled by styling the class 'search-paginate-links' :) Make 'em look good! Now, the form itself:

<form action='javascript:var q=document.getElementById("query").value;q=q.replace(/\s/ig,"%252520");d_script(q, 0);'>
     <input id='query' name='as_q' onfocus='clearDefault(this)' type='text' value='Your Query'/> <input class='preview' id='searchbtn' type='submit' value=' Search '/>
<div style='text-align:center'>Powered by <a href='http://lastword.blogspot.com'>Aditya</a></div>
</form>

To display the search, put this bit wherever you want the results to show up:

<div id='stextcont' style='position:relative;display:none'><a href='javascript:$("stext").style.display="none";$("stextcont").style.display="none";void(0);'><img id='close' src='http://images.google.com/images?q=tbn:ReDgICpawihOsM:http://lubeselector.bpmadeniyaglar.com/Images/bpClose_icon.gif' style='position:absolute;top:0px;right:0px'/></a>
<div id='stext'/>

That's it, you're done! :) Simple? Good! Go ahead and give it a whirl. Any comments and/or doubts should be asked and will be answered in the comments. Don't mail me your doubts b'cuz I want everyone to benefit from them, not just you! :)
